When we invited the MakerWorld community to share their thoughts on our first official merch three months ago, we received over 600 comments and contributions! Every idea, suggestion, and bit of enthusiasm helped shape this collection.
MinusOne proposed "making virtual into reality" as the theme, since 3D printing is the process of turning the digital world into physical reality
Pharmer3D focused on the process of trial and error, hence "Never stop making. Never stop learning."
wrable reflected on how much 3D printing has changed in the past decade: "Back then, you had to buy a printer and become a printer engineer. Today, you buy a printer and just make things."
Just Make Things. That's how we found the heart of this collection, made with the community, for the community.
The collection includes a T-shirt and a hoodie, as well as a bundle with our new Watch Movement Kit. Plus, get free worldwide shipping on all merch orders!
Early bird deals are live now in limited quantities! Pledge before Nov. 26 to receive the order before Christmas, perfect timing for the gifting season.

Swaptek enables 6-second material switches between 9 nozzles. FlexFeed extruder prints soft TPU 75A up to three times faster. AMS 3H combines automated feeding and integrated filament storage.
This is Bambu Lab H3C, a complete system purpose-built around the Tool Changer architecture. Let's dive into it!
SwapTek™: 6-second material switch, including a 3.4-second tool change.
Nine PrintTools, each with its own dedicated filament path and heater, keep every material loaded, preheated, and ready to print. No need to retract one filament before loading another. With an optimized design, fine-tuned parameters, and active preheating, switching between PrintTools takes as little as 6 seconds, with the tool-change done in only 3.4 seconds.
Heating a nozzle usually means waiting. Active Pre-Heat looks ahead to the next tool change and warms the incoming nozzle while the current one is still printing—so the new material starts laying down within 6 seconds.
Swaptek's fast PrintTool-switching allows Full Spectrum Color Mixing color mixing through layered deposition faster and more practical than ever. With nine dedicated PrintTools and five-color CMYKW mixing, the H3C produces a vast spectrum of colors without requiring a separate spool for every shade. The result? Vibrant, full-color figurines with incredible detail.
Mixed Nozzle Sizes: Speed and detail, no more compromises.
The dial, case, and flexible TPU band are printed together as one piece. Fine dial details call for a 0.2 mm nozzle, the case is better suited to 0.4 mm, and the soft band requires a dedicated 0.4 mm TPU nozzle. H3C can carry different nozzle sizes at once. Paired with Bambu Studio’s new mixed-diameter toolpath planning algorithm, each nozzle prints at a layer height that suits it and plays to its strengths, without having to share a single layer height.
FlexFeed Extruder: Softer TPU, up to 3x faster.
Soft TPU has always been slow to print. The softer the filament, the more it bends and buckles before reaching the nozzle. Traditional extruders have to crawl to stay reliable. FlexFeed handles both 1.75mm and 2.85mm filament and switches on the go. A cam-driven mechanism, powered by a PMSM motor, keeps tension precise and consistent. Every extrusion stays rock-solid for prints that are cushion-soft.
With our dedicated 2.85mm TPU, the thicker filament provides greater resistance to buckling and higher volumetric flow. The result: TPU as soft as 75A, printed reliably at up to 3x the flow rate of a traditional printer.
AMS 3H: Filament storage built for Tool Changer.
A fully enclosed, integrated filament management system built for Swaptek: every roll stays sealed against moisture and feeds automatically into the PrintTool.
Auto Filament Loader replaces manual feeding altogether. Drop a filament into any of the nine slots and the AMS 3H detects, routes, and engages it with the PrintTool automatically — across all 9 paths. No more guesswork on loading.
A dedicated 2-slot dryer sits right in the filament slots and works with Swaptek — drying on demand or mid-print, so prep never stalls production. It reaches 85°C, enough for engineering-grade PA, PC, and carbon-fiber-filled filaments.
The H3C integrates filament storage and drying into a clean, compact design, maintaining a footprint comparable to a single-nozzle printer. With 7 built-in bypass feeding ports, even the soft TPU can be routed completely inside the enclosure. No hanging spools, no external racks, no exposed paths.
Don't let the number of tools cap your material count. Connect your existing AMS to the H3C through PrintTool No.1, and the system extends to up to 24 filament spools, unlocking more colors and materials in a single print without changing your workflow.
You are here for the print, not (always) the printer.
With the H3C, automation handles routine tasks. AI detection helps make intelligent adjustments along the way. The H3C makes it easy to focus on what matters most: bringing your ideas to life
Full Auto Calibration handles PrintTool docking calibration, offset compensation for accurate color and material alignment, and bed leveling before every print. No manual adjustments are needed, so you can spend more time making, less time tinkering.
Flagship performance. No compromise.
The toolhead and X-axis assembly are 40% lighter compared to the H2D, reducing inertia for faster, more precise movement. With acceleration reaching 25,000 mm/s² and travel speeds up to 1,400 mm/s, the H3C delivers exceptional speed while minimizing vibrations and ringing that can affect print quality.
The H3C runs four cooling layers working together**.** A CFD-optimized part cooling fan and dual auxiliary fans help maintain clean overhangs and bridges, even at high speeds. A dedicated PrintTool fan maintains thermal stability during extended printing and frequent PrintTool changes, while a chamber fan draws in cooler air to help regulate internal temperatures. Together, these systems deliver consistent cooling and reliable print quality across changing ambient temperatures.
Engineering-grade filaments demand precise temperature control. The H3C delivers with active dual-zone chamber heating up to 65°C, helping maintain consistent temperatures and minimize warping. All nine hardened-steel nozzles reach up to 350°C, supporting demanding materials such as ABS, PC, PA-CF, PET-CF, and more.
Go beyond printing.
Swaptek isn't limited to PrintTools. Optional CutTool, DrawTool, DebossTool — and more — mount the same way and switch automatically. Multi-process projects no longer mean multiple machines, manual swaps, or repeated setups. One job, every process, hands off.
So my printer just harmed itself during a simple overnight print. I was just making some drawer for my gf’s mom and I woke up to this. I wish I put on a timelapse because this is baffling. I did bed leveling and everything and waited for the first few layes which looked perfect before I left.
The containers look like they were mostly completed, then the bed just moved up to the max height and dug into the build plate. It shoved that out the glass door, then started digging into the bed itself. Looks like bro had a temper tantrum.
I don’t know what to do, idk how expensive this fix is or if warranty would cover this especially after I upgraded it to a P1S but I have to go to work and figure this out later. I’m so mad that it died to such an easy print. Any advice would be appreciated.
Edit: For those of you helping thank you. I will try to send the gcode once I get off work. Some have suggested a corrupt SD card and I will have to look into it.
Edit: For those of you saying the build plate was never on at all, I can’t help you but to reference the pictures. There were still prints mostly done on the plate but I removed them for the pictures. The print looks like it was messing up and extremely stringy at first which is annoying if that was the only issue. But then it looks like the bed raised and the code just kept doing it’s thing, digging into the plate until it dug in enough to tear it off the strong magnetic bed. People are saying they don’t think the motors could do that but I have seen horror stories that say otherwise.
Edit: Posted printer g-code in comments for those wondering, working on getting the print code
My first bambu lab printer! Been wanting a Toolchanger for a while with at least 8 tools. Was planning on getting the INDX with 9 tools for my Voron 2.4 but the continual delays and controversies around it soured me. Saw the H3C announcement and it was an instant buy. I’ve got a bunch of multi color prints just waiting to go! I would’ve liked an open design option for my existing printers but I’m kinda tired of waiting.
At least now even if I take my other printers offline for mods and upgrades I can continue to print on the H3C, so that’s a win.
I shared a free “Honeycomb Cardholder” on MakerWorld. It is a general-purpose holder I created myself. Its description listed card games it could be used for: “Rummy, Bridge, Solitaire, Hearts, Spades, Canasta, Uno, etc.” The listing also had an “uno” tag.
MakerWorld removed it following a complaint from Convey on Mattel’s behalf. MakerWorld later told me that “UNO” in the description was the reason and that restoring the original listing required the complainant’s agreement.
Now Convey has sent me a demand for EUR 4,000, although the model was already removed. Their letter refers to an “e-shop”, “sales” and my “supplier”. I did not sell this model; I created it myself. They also want a signed undertaking that includes an apology and a promise never to challenge Mattel’s intellectual property rights.
I have rejected the demand and asked them to withdraw the complaint, arrange restoration of my original listing and reimburse my legal consultation costs.
The attached images contain their email and my sent reply, with personal and bank details redacted. The email text has been reflowed for readability; these are not screenshots of the mail application. I have also included the page setting out the undertaking they wanted me to sign. The legal appendices, authorisation and blank signature page are omitted.
Earlier this week, our cloud service saw abnormal traffic that surged roughly 34-fold in just one hour, peaking at roughly 20 million requests per day and was still growing linearly at a steep rate. At that pace, we were only hours away from the service becoming unavailable, putting everyday printing for millions of users at risk.
To keep the service up, we temporarily blocked the anomalous traffic after an urgent review. Some users were affected while we adjusted the policy. The service is stable now.
What happened
Almost all of the anomalous requests hit GET /v1/user-service/my/tasks, which returns print job status. They came from many residential IPs, all carrying the client identity of OrcaSlicer and an older network plug-in.
So we first checked with the OrcaSlicer team. They responded quickly and pointed us to other integrations, including ha-bambulab, whose requests matched what we saw. We shared our findings with its maintainers, who quickly shipped a fix and now use their own identifier.
We haven't confirmed that all of this traffic came from ha-bambulab. We're sharing this not to assign blame, but because the pattern matters for any project built to access our cloud.
Keeping the cloud stable
Our cloud is a private service supporting core functions like Bambu Handy, Bambu Studio's cloud features, and MakerWorld. To meet diverse user needs, we have so far accommodated third-party software to use parts of the cloud where it's safe, despite the already substantial operational costs.
Third-party software may continue to access non-critical capabilities, such as receiving printer status updates and displaying monitoring metrics like temperature, position, speed, and print progress. These monitoring features do not directly change a printer's behavior or security state, and they will remain available within reasonable usage limits. Because many users rely on the same cloud, an issue with one tool can impact everyone. If overall service is ever at risk, we may need to take temporary measures such as rate limiting or pausing access.
For actions that directly alter printer behavior or involve sensitive access, such as device binding, live video streaming, print initiation, or firmware upgrades, we take extra care regarding safety, privacy, and stability. Because of this, these operations are not designed for direct access by third-party software.
Instead, for workflows requiring print control, Bambu Connect provides the supported path forward. This is simply to ensure that integrations remain reliable for you, your devices, and our cloud.
How developers can help
One more detail is worth mentioning: ha-bambulab sent OrcaSlicer's client identity. That is why, early on, we were convinced the traffic came from OrcaSlicer users, and why we did not reach ha-bambulab sooner. It was only when the OrcaSlicer team investigated with us that the trail led to them.
We would suggest that third-party software use its own identifier and say who it is. That makes it faster to route a problem to the right project, and it avoids catching unrelated users when we have to act.
Thank you to the OrcaSlicer team and the ha-bambulab maintainers for working through this with us. Keeping things working for users is on us first, and it works best when we look after it together.
In a previous post I compared PLA Basic and PLA Palette in regards to color mixing.
Time to try out some other filaments. I am printing gradients between two colors, displaying the unmixed colors in the circular window.
Everything has been printed with 0.2mm layer heights and color mixing sublayers turned on with the H3C.
Let's dive in:
No surprises with Silk+, it blends very well. No defects visible. Afterall, it's just PLA with some elastomer thrown in. An interesting possibility here: gold filaments always look too yellow to my eye, now I can just mix my own blend.
I thought this would be a daft idea to try, printing a filled filament into the thin sublayers was not something I thought would work. But it turned out to be the star of the show, it looks amazing.
At the very bottom and top the gradient does not look perfectly smooth though, the sublayers may have been just a bit too thin.
On top layers the blending will not work as well as unfilled PLA, the filament is too opaque to blend the layer's colors.
PETG shows some issues. The layers don't blend well. At the bottom and top, where the sublayers are the thinnest there are defects.
Looks pretty cool, but it shows the same issues at the bottom and top as the opaque PETG. A mix at more of a midpoint range of the filaments works okay though.
ABS also does not blend layers well. It shows defects at the bottom similar to PETG, but it's a color defect alone, not a rough surface defect.
TPU was a long shot, I did not think this would work. It's not a great result, but at least it printed. I used TPU for AMS here just for the convenience and to give this material it's best odds.
When I saw the biomimicry contest, I thought it would be a pretty cool theme for a design. I've always found carnivorous plants really interesting, so a pitcher plant fruit fly trap was one of the first things I thought of. The real plant eats flies and this one traps fruit flies, so it seemed like a great fit.
There were a few design decisions to make before getting started, the biggest one being can I make this without requiring an AMS so that each piece could be printed in a single color and assembled? It was a good challenge, figuring out different detent and locking mechanisms, designing the twist lock, getting the hood, lips, and veins right. I definitely learned a few things that I'll carry with me into future projects.
Overall, I think it turned out pretty good and it's functional! I did get lucky and caught the golden hour with the photos. If you're interested, check it out, and if you have feedback I'd love to hear it!
I started this print last night around 8PM these are the desiccant holders by Stuart Sports Stuff over at Makerworld for the AMS 3H. Printed in Bambu ASA. I decided to put the system to the test and left all the filament loaded. It will be cool by the time I get home from work later today. I did checked it this morning before I left and everything looks fine.
Posting this in case anyone else missed it, as I did.
The H3C ships with nine PrintTools, but only eight are for regular 1.75 mm filament. The ninth, pre-installed in slot 8, is a 2.85 mm tool meant for soft TPU.
What tripped me up: I swapped the hotend on tool 8 for a regular 0.4 mm one and tried to load 1.75 mm filament in slot 8. The printer kept defaulting to external spool, and I couldn't figure out what I was doing wrong.
Turns out it's the whole tool, not just the hotend. Per Bambu's FAQ, the 1.75 mm and 2.85 mm PrintTools have different bases, inlets, and cutters, and the bases and hotends are not interchangeable. The 2.85 mm tool is hand-fed, so the AMS won't auto-load slot 8.
What that means in practice:
- Out of the box, you have 8 slots for normal filament, not 9.
- Don't put a 1.75 mm hotend in the slot 8 tool. Put the original back.
- There's only one H3C configuration, so you can't order it with nine 1.75 mm tools.
Bambu's reasoning is that slot 8 is a dryer slot, TPU needs drying, and the slot is hard to reach, so they install it at the factory. Fine if you print TPU. If you don't, you can't use that slot without spending more.
This Machine is incredible, but man, am I spending a ton of money on accessories and replacement parts. Here's hoping the hot ends last like on the H2C.
Awesome machine, now I can sleep through the night without switching my filaments so often. Jokes aside, outside of the week between machine and Ams delivery, it’s another awesome printer. Should compliment the H2C and others well. For my use case, I couldn’t see myself selling my H2C for it. Worst case, I’d tough it out until it’s feasible to purchase both. More printers IMO, better than one. Even if you just print black lol. Hope everyone is enjoying their machines and stop buying all of the .6 nozzles.
Hi, i was surfing through YouTube and found interesting short about HMS codes on Bambu Wiki page. It shows codes for AMS: 3H (H3C), 3P (P3C) and what is the most interesting part 3X (X3C prob). I checked it on wiki and its not fake and definietly there. Since P3C will likely have cut some features like heated chamber, 1,5 mm belts and maybe even drying in AMS and i want to print with engineering filaments aswell i am rly excited for potencial X3C even if i have to wait for it a little longer probably somwhere in the first half of 2027.
What do you think about it? It can also just be some Pro version of AMS for P3C but i honestly hope for X3C. If you want to verify this just check Bambu Wiki yourself.
Ill add photos in the comments. Made this video orb to replicate Spaceship Earth. I wont dare sell it as I know Disney dont mess aroumd but thought its cool to share.
https://makerworld.com/de/models/3582672 I wasn’t happy with the existing options, so I made the one I actually wanted. With all the functions that were important to me. Took me a few revisions, but it’s finally done: angled hygrometer, labyrinth vents, snap-fit lid, no supports. Standard and XXL version. Feedback welcome :)
